Marlon and michelle have to graph a function with the equation y=x2and are having to debate about which is the most important element to get started, the domain or the range . which of them is correct?

Correct answer is the domain.

Step-by-step explanation:

A domain is the input set of a function.

A range is the output set of the function.

It is more  important to know the domain of the function to be able to determine the corresponding output set so the function can be graphed. To start with the domain is very useful because every domain element has a corresponding unique output element.

Suppose you started with the range element of 9. The input set for an output of 9 is {-3,3}. This makes it hard to match up the elements. This example highlights why it is important to start with the domain rather than the range.

the correct answer is:

Carlos could have written 0.333, 0.334, and 0.3335.

hope this helps or is correct!
